Definition at line 353 of file ossimVisitor.cpp.

References ossimRefPtr< T >::get(), and m_view.

◆ visit()

void ossimViewInterfaceVisitor::visit ( ossimObject * obj )

virtual

Calls ossimViewInterface::setView if obj cast to ossimViewInterface*.

On success a property event is sent to output side so that things like ossimCombiner can reinitialize if needed.

Parameters

obj	Object to visit.

Reimplemented from ossimVisitor.
